well i have had my 115 running now for about i month. upgraded from a 55 gal. so far i got a alot of coraline algee already started to cover the sides and back, along with my powerheads and my water outlet. my tank levels have been good 8.2 ph, <10ppm nitrates, 400ppm cal, 2.8 alk. i have about 20 snails different variety, 10 red leg hermits, lawnmower blenny, rainford goby, banzai cardinal, spotted cardinal, coral beauty, tomatoe clown, and a naso tang. i willl have to say that this tank i definately easier to maintain than my 55 gal. also i am running 550watt of vho with 3 actinics, 2 white actinics. corals seem to be thriving, all my tank mates seem to be doing better than my 55 gal. so my experience is so far is bigger is better. i am glad i made the change.
